What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Start with the exact device model and hardware revision. On the manufacturer’s official support page and in its companion app, check the installed firmware version, update method, recent firmware releases or security notices, and any stated end-of-support date. These are separate checks: an update feature—or a history of past updates—does not by itself promise continued security support.
1. Identify the exact device
Record the model number and hardware revision from the device label, its app, or the original packaging. Then find the matching product page on the manufacturer’s website. Confirm that it applies to your hardware revision and region: products with similar names can use different firmware or have different support information.
2. Find the installed firmware version
Open the device’s app or settings interface and note the displayed firmware or software version. If shown, record when the device last checked for or installed an update. Menu names and locations vary, so use the product’s manual or official support instructions rather than assuming that a particular setting is present.
NIST’s Smart Home Update Survey Questions lists a device-app message or notification and the manufacturer’s website among ways people may learn about an available update. Its listed options also include manufacturer email or text. NIST Smart Home Update Survey Questions

3. Check for and install updates through the documented method
Use the manufacturer’s app, device interface, or other documented update process. Check whether the device reports that its firmware is current, whether an update is available, and whether updates happen automatically or require you to start them.
NIST’s technical catalog describes both remote and local update mechanisms. It identifies authorization and verification that updates come from a valid source as important update capabilities; examples include digital signatures, checksums, and certificate validation. Use the manufacturer’s documented channel rather than an unofficial firmware file or an unverified download. NIST technical catalog for IoT device cybersecurity capabilities

4. Look for dated releases and security notices
On the support page for the exact model, check the firmware history, release notes, security bulletins, and manufacturer notices. Look for dates and descriptions of fixes, not just a version number. A device can show a current version while still having no clear evidence that the manufacturer continues to maintain it.
5. Verify the support commitment separately
Search the official product documentation and lifecycle notices for terms such as “security update support,” “end of support,” and “end of life.” Look for a statement or end date tied to your model, rather than a general policy that may not cover it. NIST’s manufacturer-information catalog treats communication about unsupported devices and the security impact of ending support or functionality as relevant information for customers.

If the published information is unclear, contact the manufacturer in writing. Include the exact model, hardware revision, and region, and ask whether security patches are still planned and whether the company states an end date. Keep the reply and its date because support information can change.
What to compare when choosing a device
Compare the details that show both how updates work and how long support is expected to last:
Rank #4
- ENDLESS POWER FROM SOLAR ENERGY: Just 45 minutes of direct sunlight powers the camera for a full day of use, while the built-in battery lasts up to 180 days on a single charge during cloudy days. Solar charging requires temperatures above 32°F.△
- EASY WIRE-FREE INSTALLATION: Place the Tapo SolarCam C402 KIT where you need it without relying on nearby outlets. Install the camera and solar panel together or separately using the included 13 ft cable for flexible placement.
- PRIORITIZE WHAT MATTERS: Set activity zones to monitor specific areas for motion or people. Free person and motion detection helps reduce unwanted alerts and notifies you when activity is detected.
- VERSATILE VIDEO STORAGE: Store footage locally via a microSD card (up to 512GB)* or via cloud with a Tapo Care cloud subscription. Tailor your security to suit your needs, whether indoor or outdoor, you have the storage option you need.
- FULL-COLOR 1080P, DAY AND NIGHT: See clearly in low light with a large-aperture lens and built-in spotlights. Capture full-color night vision up to 30 ft away to monitor for possible intruders or motion.
- Support period: a published duration or model-specific end date.
- Update history: dated firmware releases and security notices.
- Update process: automatic updates versus updates you must check for or install manually.
- Notifications: how the manufacturer tells customers an update is available.
- After support ends: the manufacturer’s explanation of security implications and what functionality remains.
NIST guidance discusses update criticality and timing, possible update impacts or dependencies, and end-of-support communication as useful customer information. It does not establish one universal minimum support duration for all consumer smart-home devices.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.If support has ended or cannot be confirmed
Read the manufacturer’s notice for the security implications and any functionality that will stop working. If you cannot find a model-specific answer, request one from the manufacturer before treating a general policy or an old firmware release as proof of ongoing support. NIST describes software updates as central to vulnerability management because they allow software to be changed when vulnerabilities are found and remediated. NIST SP 800-213A
